Appli-cation filed. .Tune 25, 1925. Serial No. 39,489.

To all whom @'25 may concern:

Be it lnown that I, HENRY NnvisoN, a citizen of the United States,residing at Lincoln Park, in the county of W'ayne and State ofMichigain'have invented certain new and useful Improvements in lVindows,of which the following is a specification.'

rlhis invention relates to certain novel and useful improvements inwindow construction, and is designed particularly for use with sashadapted to slide vertically in their frames. p

The objects of my invention are 'as follows: first, to provide for theVswinging of the sashesoto an approximately horizontal position withinthe room for cleaning; second, to provide a swinging window havingV aweather tight joint between the sash and its frame; third, to provide aswinging sash having non-rattling features; fourth, to provide aswinging window that .is capable of being economically installed in theordinary type of sash and frame with its sash cord and weights; andV-fifth, to provide for eX- ceptionally easy lsliding' operation by reduc,ing the friction of the sash within its frame. l attain these objectsbythe mechanism illustrated in the accompanying drawing, in which Y fFigure l is a vertical section of the window and sash in a'planeparallel to and at the's'urfaceV ofthe glass in the lower sash; Fig. 2,a horizontal section on the line 2 2, Fig. 2; Fig. 3, a horizontalsection on the line 3 3, 1,; Fig. 4, a horizontal section on the line 44, Fig. 1; Fig. 5, a vertical section cn the line 5 5, Fig. 4; Fig. 6, avertical section on line 6 6, Fig. 1; Fig. 7, a vertical section on line7 7, Fig. 6; Fig. 8, a vertical section on line 8 8, Figfl,

showing both sashes swung to a cleaning posit-ion; Fig. 9, a verticalsection von line 9 9, Fig. 1; Fig. 10, a side view of the upper ends ofthe metal guides 1n the window casing; and Fig. 11, a vertical sectionon Yline 11 11, Fig. 9.

Similar numerals refer to" similar Vpar-ts throughout the several views.

YrEhe window sash show-n' in the drawings is of the ordinary type,having ran upper cross member 1. a lower cross member Y2. a verticalstile 3,v and a glass `pane il. Metal shells 5, are'fastened by screwsGpinthe vertical grooves of the Wi'ndowcasing 7. The

- metal-shell 5 .is formed --with van open sfide toward the stile 3, theopen side acting as a groove in which slides the metal shell 9. Metalshell 9 is formed with a flange 10 against which the stile 3 contactswhen the window is swung to a closed position.

Teather strip 11 is formed from metal intoa convex shape as shown inFig. 3 and is fastened by folding the edge 12 around the inside vedge ofthe metal shell 9. The corner 13 of the nieta-l shell 5 is formed with aslight depression which 4allows ythe rounded edge 12 of the weatherstrip 11 to assemble Esnugly as shown. vThe rounded `edge 12 allows thewindow to be easily swung from an open yto a closed position 'withoutdamaging the corner of the stile 3. The weather strip 1.1 and metalshell 9 extend for the full height `of each stile and slide with thestile asl the sash is operated up and down within the groove of metalshell 5. A hook 14 is formed by punching a hole in the wall of the metalshell 9 and pressing a portion of the metal into the shape as shown inFig. 11. Sash cord 15 is looped around the hook 1li and the end of thesash cord is retained by clip 16. Thus the sliding of the window sashtogether with the metal shell 9 and weather strip 11 is facilitated bythe or- 'dinary sash cord 15, operating over pulleys 17, they sash cord15 being attached to the usual sash cord weight which operates withinthe casing and which is not shown in the drawings.' Also the sliding ofthe window sash is further facilitated by the action of the roller pins18 which lit within holes in the walls of the sliding metal shell 9 andbear against the inside of the fixed metal shell 5. The roller pins 18are rounded at their ends and are retained from end motion by thel endwalls of the metal shell 5.

In a groove at the bottom of the lower cross'memher 2, of each sash isfastened a bracket 19 having a `cam 20, which extends through a hole 2 1in weather strip 11 into the groove formed by the walls of sliding shell9. When the window sash is in a vertical and sliding position, the cam2O has its shortest length lying in a horizontal plane and its longestlengthin a vertical plane as shown in Fig. 6. In' this position vtheshortest lengthgiit's, without binding, between the walls Vof the shellT9. TNlien the window is swunginto a reclining position for cleaning,

'as shown in Fig. 8, 'the 'longest length of the 'cam '20 'movestlfirough an angle of approxi- Cil lill

matel)Y 900 and then lies in a horizontal plane. The longest length ofthe cani 2O is made slightly greater than the distance between the wallsof the metal shell l) and thus binds or wedges itself into a lixedposition which in turn locks the window in position for cleaning. Thebracket 19 is further ex tended into a round pivot Q2 which turns withinthe bearing block Q8, the bearing block 223 being suitablyv fastened tothe inner walls of the shell t). The pivot Q2 titting within thebearing' block thus forms a swivelline connection between the lowercross member 2 of the window sash and the sliding metal shell 9. It isto be noted that the pivot 22 is ccceutricaltv located toward the insideof the sliding sash. This allows the bottom ot each sash to swing' clearof the liange ltl, when the sashes are swung to a cleaning position asshown in Fig. S.

At the top of the upper cross member l of each sash is fastened a lochplate 2l which has a tongue Q5 which lits between the walls, of thesliding` metal shell il. "he tongue has a slot 26 through which operatesthe cord l5. yl`he tongue' not only operates as a lock to keep thewindow sash in a vertical sliding position but also forms a weatherprotection for the inside of the sliding' metal shell 9. The lock plate2l is preferably made ot pressed metal with a linger hole 2T andelongated screw holes 28 which permit. ot sliding' the lock plate 2lwith itstongue out ot engagement with the sliding' metal shell Q. thusallowing` the window to swivel inward to a cleaning' position.

lt is to be noted that the fixed metal shells extend for the full lengthof the ca. ing and are made with a recess 29 which tits around thepullelvs 1.7. Also the upper ends of the sliding metal shells 9 are madewith a slot bl which allows the metal shells 9 together' with its sashto slide up to the top of the easing without interfering` with thepulleys 1T. In Fig. l0, the sliding metal shell 9 is shown at the upperend of its travel.

To allow the upper sash to be swung` inwardlv over the lower sash, asshown in Figi'. S. it is necessary to malte the upper sash slightly.'narrower than its mating lower one. 'this necessitates moving the fixedmetal shell .3. lor the outer sash, in toward the center ot the windowsash to accommodate the narrower upper sash. This is economicallhvacconn'ilished bv using a wood ller strip 30, as shown in 2, this inturn allowing the use of the same sized slidingl shell 9 and lixed shell5 for each sash.

To operate te a cleaning position, operator slides both sashcs to thebottom of the casing, slides the lock plate 2l out of engagement withthe sliding metal shell 9 and then the sash will swivel in bearing block23 until itv occupies a position as shown in Fig'. S, when it will belocked by the Cain. 2O within. the sliding shell tl, from furthervertical movement.
